RE: [Jfs-discussion] JFS kernel BUG

[Theo <tg...@ia...>]

To add, my one JFS filesystem is corrupted now. The filesystem that is
corrupted wasn't the fs that was exported. I figured this filesystem got
nailed after the nfs problem I had, since this fs is being wrrite a lot to.

I'm able to reproduce the problem now. If someone needs nmore info I will
gladly help where I can. Just shout.

Most of the faults are this:

Jul 25 19:38:29 alderaan kernel: assert(le32_to_cpu(iagp->wmap[extno]) &
mask)
Jul 25 19:38:29 alderaan kernel: kernel BUG at jfs_imap.c:1065!
Jul 25 19:38:29 alderaan kernel: invalid operand: 0000

and a few

Jul 25 19:14:00 alderaan kernel: ialloc: diAlloc returned 28!
Jul 25 19:14:00 alderaan kernel: assert(iagno < imap->im_nextiag)
Jul 25 19:14:00 alderaan kernel: kernel BUG at jfs_imap.c:1033!
Jul 25 19:14:00 alderaan kernel: invalid operand: 0000

My two cases of JFS corruption/OOPS/KernelBUG as I reported in earlier
posts to this mailing list were both boxes running knfsd. We use knfsd
fine with ext2 and reiserfs (with the 2.4.7  kernel)
